Web browser based end-to-end encryption method
The granted patent (Publication Number: US11824840B1) discloses a method and system for implementing web browser-based end-to-end encryption between a sender and a recipient over the internet. The method involves running web browsers on both devices, downloading sets of files containing encryption and decryption scripts, composing and encrypting messages on the sender's device, and decrypting and displaying messages on the recipient's device. The integrity of the files is verified through cryptographic analysis and comparison with trusted values, ensuring secure communication between the devices.
Furthermore, the patent also describes a system for verifying the integrity of root documents in web pages downloaded from untrusted servers. By obtaining cryptographic values from trusted sources and performing cryptographic analysis, the system ensures that the root documents are free from malicious code. The use of public keys, digital signatures, and reference hashes adds an extra layer of security to prevent unauthorized access or tampering with the downloaded files, thereby enhancing the overall security of web browsing and communication processes.
